Do not wear loose clothing or jewellery. They can be caught in moving parts. Preferably wear rubber gloves and non-slip safety footwear. Wear protective hair covering to keep long hair out of the way.

1. Do not overreach.

Keep proper footing and balance at all times.

1. Stay alert.

Watch what you are doing. Use common sense. Do not operate the tool when you are tired.

1. Use appropriate tool.

The intended use is described in this instruction manual. Do not force small tools or attachments to do the job of a heavy-duty tool. The tool will do the job better and safer at the rate for which it was intended.

⚠ WARNING! The use of any accessory or attachment or performance of any operation with this tool, other than those recommended in this instruction manual may present a risk of personal injury.

1. Maintain tools with care.

Keep the tools in good condition and clean for better and safer performance. Follow the instructions for maintenance and changing accessories. Keep all controls dry, clean and free from oil and grease.

1. Check for damaged parts.

Before using the tool, carefully check it for damage to ensure that it will operate properly and perform its intended function. Check for misalignment and seizure of moving parts, breakage of parts and any other conditions that may affect its operation. Have damaged guards or other defective parts repaired or replaced as instructed.

Additional Safety Instructions for Pneumatic Nailers

• ALWAYS wear safety glasses.

• ALWAYS wear ear protection.

- Only use fasteners of the type specified in the manual.

- Do not use any stands for mounting the tool to a support.

- NEVER use the tool for any other purpose than specified in this manual.

- NEVER use this tool on scaffolds, stairs, ladders or similar workplaces.

- Don't use the tool to close cases or crates.

- Don't use the tool for attaching transportation safety devices e.g. on vehicles and carriages.

- Before use check proper function of contact trip. Never use this tool when either trigger switch or contact trip is damaged.

- Use quick-action couplings for connection to the compressed air system. The non-sealable nipple must be fitted to the tool in such a way that no compressed air remains in the tool after disconnection.

ENGLISH

• ALWAYS use clean, dry compressed air. Do not use oxygen or combustible gases as an energy source for this tool.
• The maximum allowable air pressure of the tool shall NEVER be exceeded.
• Only connect this tool to an air supply where the maximum allowable pressure of the tool cannot be exceeded by more than 10%. In case of higher pressures, a pressure reducing valve including a downstream safety valve shall be built into the compressed air supply.
• Only use hoses with a rating exceeding the maximum operating pressure of the tool.
• To prevent an unnecessarily high noise level, increased wear and resulting failures, the nailer should be operated with the lowest pressure required for the work process.
• DO NOT use oxygen, combustible gases or any other reactive gases for operating compressed air. Danger of explosion and/or serious personal injury may result.
• Before transporting the tool, disconnect it from the compressed air system, especially where ladders are used or where unusual physical posture is adopted while moving.
• Disconnect the tool from the air supply when it is not in use.
• Avoid weakening or damaging the tool, for example by:

- punching or engraving

– modifications not authorised by the manufacturer
– guiding against templates made of hard material such as steel

• dropping or pushing across the floor
  – applying excessive force of any kind
• Do not use the equipment as a hammer.

WARNING! Keep the nailer, loaded or unloaded, pointed away from yourself and others. Serious personal injury may result.

• While working, hold the tool in such a way that no injuries can be caused to the head or to the body in the event of a possible recoil due to a disruption in the energy supply or hard areas within the workpiece.
• NEVER actuate the fastener driving tool into free space.

• In the work area, carry the tool at the workplace using only one handle, and NEVER with the trigger actuated.

• Consider the conditions in the work area. Fasteners can penetrate thin workpieces or slip off corners and edges of the workpiece, and thus put people at risk. The length of the nails used should be no longer than the thickness of the workpieces. If the nails are longer than the workpiece thickness this could cause a rebound of the nails if the workpiece is placed on a hard surface e.g., concrete, steel.

• Do not drive fasteners close to the edge of the workpiece. ALWAYS keep a distance of at least 25 mm from the edge of the workpiece so nails will not destroy the workpiece.
• Do not drive fasteners on top of other fasteners.
• Only use spare parts specified by the manufacturer or his authorised agents.
• Have repairs carried out only by the manufacturer or authorised agents having due regard to the information given in the manual and using the appropriate tools and equipment.
• Replacement of contact trip spring is recommended every 3-4 years to ensure personal safety.
• Do not disassemble or block any parts of the fastener driving tool such as the safety yoke.
• Have the tool serviced properly and at regular intervals.
• ALWAYS wear safety gloves to reduce the risk of personal injuries.
